Digital BW, The Print

Of _course_ it is relevant.  The whole purpose of this list is to discuss
black and white printing.  Black and white prints normally come from black
and white images, and the latter are often produced with black and white
film and filters.  It's about as relevant as anything can get.

This entire discussion, in fact, is far more important than you seem to
realize, because it has some pretty serious implications for those trying to
reproduce one type of B&W print from something other than one type of B&W
image.  In particular, it is critically important that anyone shooting
color--such as digital color--and trying to get B&W from it understand these
principles, so that he or she can understand why certain results can be
produced, whereas others cannot.

No, you see approximations.
